Cognex DataMan 300 tackles difficult to read barcodes with improved algorithms and intelligent lighting
1 min read
Cognex says its DataMan 300 fixed-mount industrial ID reader with its 1DMax+ algorithm offers increased barcode read rates. Using 'Hotbars' technology it can handle the most difficult ID code-reading applications on even the highest speed lines, says the company. Reading performance for 2D matrix and difficult-to-read DPM (direct part mark) codes has also been significantly improved by a major upgrade from the 2DMax to the 2DMax+ algorithm.
1DMax+ with patent-pending Hotbars technology, says Cognex, is a breakthrough in image-based barcode reading. Invented by 31-year company veteran Bill Silver, Hotbars uses texture to locate barcodes at any orientation and then extracts high resolution 1D signals for decoding. The 2DMax+ algorithm is also an upgrade from existing 2DMax technology offering enhancements in reading poorly marked or extremely damaged codes at high line rates.
Integrated and controllable modular lighting and optics make the DataMan 300 series easy to set-up and deploy. The user can purchase just one model and choose the appropriate lens for their required working distance and field of view. The controllable, field-changeable lighting modules allow the user to create the best possible lighting for their part and ensure optimal read rates.
2D DPM code reading is inherently difficult due to the manufacturing processes that parts undergo. DataMan 300's intelligent tuning technology automates the settings of the integrated lighting to find the optimal light set-up to form the best possible image of each part.
There are two DataMan 300 series models. The DataMan 300 provides standard resolution of 800 by 600 pixels and the high resolution DataMan 302, suitable for reading very small DPM codes on small components to ensure full part traceability, offers 1,280 by 1,024 pixels.
